System and method for understanding text using a translation of the text

ABSTRACT

Devices and methods for determining the content of a first segment of text in a first language, using a second segment of text in a second language. The second segment of text is a translation of the first segment of text.

RELATED APPLICATION

The present application gains priority from U.S. Provisional Patent Application 62/345,989 filed Jun. 6, 2016 and entitled “Understanding Text Using a Translation in another Language”, which is incorporated herein by reference as if fully set forth herein.

FIELD AND BACKGROUND OF THE INVENTION

The invention, in some embodiments, relates to understanding of the meaning of a written text, and more particularly to methods and systems which enable understanding of a text in a first language using a translation of the text into a second language.

The problem of understanding text by computers is well known. For example, full understanding of an input text is required in order for a computer to automatically generate an output text in another language, such that the output text has the exact same meaning as the input text, in a process known as “machine translation”. Another use for automatic understanding of a written text is the extraction of knowledge from the text, for example for generating recommendations of content to a TV subscriber based on textual summaries provided by content providers, which requires full understanding of the input text in order correctly judge what content is expected to be of interest to the subscriber.

A naïve approach to the task of understanding text would be to lookup each word of the text in a dictionary. Unfortunately, this approach often results in an inaccurate translation, as it disregards the existence of ambiguous words, which have multiple distinct meanings. For example the word “numbered” has multiple meanings, including, (i) marked by a number, as in “The pages of this book are numbered”, and (ii) limited in number, as in “The old man's days are numbered”. In some cases, the context of the full sentence in which the ambiguous word appears may indicate which of the multiple interpretations, or meanings, of the ambiguous word, is the correct one for understanding the text. However, there are cases in which it is impossible to determine, based on the context, which of two meanings is the correct one. For example, in the sentence “The days of the paper calendar are numbered” it is impossible to tell whether the meaning is that the day of the paper calendar are marked by numbers, or that the days of the paper calendar are limited in number.

Additional examples of ambiguous English sentences, containing words having multiple meanings, which cannot be resolved from their local context, include: “Being in debt attracts a lot of interest from bankers”, “The invention of the wheel created a revolution”, and “Airlines process lost luggage on a case by case basis”. (All the above ambiguous sentences are taken from http://www.businessballs.com/puns-double-meanings.htm).

The problem of ambiguous words with multiple meanings is well known and many solutions for it have been proposed. Many of the proposed solutions rely on a statistical approach, in which a large amount of text is analyzed, in advance, to determine relative frequencies of each of the potential meanings of each ambiguous word by counting occurrences of these meanings and storing the counts in a database. Subsequently, when encountering the ambiguous word in a text to be understood, it is assumed that the meaning of the word is the most frequently appearing meaning according to the advanced analysis, thus providing a high probability of selecting the correct meaning of the ambiguous word.

An improvement to the statistical approach described above, which adds context analysis to the statistical approach, is disclosed in http://anthology.aclweb.org/P/P91/P91-1017.pdf. In accordance with this method, rather than counting occurrences of single words, the improved method counts occurrences of pairs of words that appear to be related to each other in the analyzed text, and then selects the most frequent interpretation for the pair of words. In the example provided above, of “The days of the paper calendar are numbered”, one may count occurrences of the pair {days/numbered} in which the word “numbered” is used with the meaning of “marked by a number” and in which the word “numbered” is used with the meaning of “limited in number”. Most probably we will determine that when combined with the word “days”, the word “numbered” is more frequently used to mean “limited in number” rather than “marked by number”, and therefore the interpretation “limited in number” would be selected.

An additional improvement disclosed in the article mentioned above is to apply the statistical test, not (only) in the language of the analyzed text, but (also) in a second language in which the analyzed word is not ambiguous, and has a single meaning. For example, even though the word “numbered” is ambiguous in English and corresponds to two different meanings, in Hebrew those two meanings are each associated with a different word: “

” (pronounced meh-moos-pah-REEM) for “marked by number” and “

” (pronounced sfoo-REEM) for “limited in number”. In accordance with this improved method, the occurrences of each of the two Hebrew words (or pairs of words) are counted over a large amount of Hebrew text, and it is assumed that the resulting probabilities measured on the Hebrew text are reliable approximations of the corresponding probabilities of the multiple meanings of the ambiguous word in English. The authors of the article claim that counting the likelihood of a word meaning, or of the meaning of a pair of words, in a different language may provide better results than counting the likelihood of a corresponding word meaning in the language of the original text.

However, all the described solutions for determining the meaning of an ambiguous word, succeed in increasing the likelihood of achieving the correct interpretation of the word, but are far from providing 100% accurate understanding of the text. Additionally, the more successful the solution, the more complex, time consuming, and expensive it is to implement. Methods that rely on statistics of pairs of words require a much more extensive analysis of a large amount of reference text and a much higher number of entries for which occurrence data must be stored.

There is therefore a need in the art for a method for determining the meaning of a text including ambiguous words at a high accuracy rate, while being simple, robust, fast, and inexpensive to implement.

DESCRIPTION OF SOME EMBODIMENTS OF THE INVENTION

The invention, in some embodiments, relates to understanding of the meaning of a written text, and more particularly to methods and systems which enable understanding of a text in a first language using a translation of the text into a second language.

It is a goal of the present invention to understand the meaning of a segment of text, using a translation of the text in a second language to disambiguate ambiguous words having multiple meanings in the language of the original text.

As described hereinabove, there are many approaches for disambiguating the meaning of words in a text when attempting to understand the meaning of the text. The existing approaches typically include advance analysis of a significant volume of text, so as to determine the statistical probability of an ambiguous word to have a specific meaning, whether independently or in context with another word.

However, such prior art methods require significant time, computing, and storage resources for carrying out the advance analysis and for storing the results thereof. Additionally, implementation of such methods is often prohibitively expensive.

By contrast, as will be described in detail hereinbelow, the present invention provides methods and systems for understanding text using translation of the original text into a second language, without requiring any advance analysis or processing of large amounts of text. Additionally, the methods and systems of the present invention do not require storage of statistical databases, and therefore require use of less memory than prior art methodologies. The methods and systems described herein also reduce the processing power required for understanding the text since no advance analysis is required, and since translation can be carried out in real time, as the text is obtained, as described in further detail hereinbelow.

The solution proposed by the present invention is applicable to a sub-class of the general problem of ambiguous words—the case in which the text to be understood is available in multiple languages. For example, this may be the case when extracting knowledge from sub-titles of a movie—typically the movie is provided with pre-prepared sub-titles in two or more languages, making the methods of the proposed solution applicable. Another example is when carrying out machine translation of text in a first language, which text was previously translated, by whatever means, to a second language, in order to generate a translation of the text into a third language.

The availability of a translation of the text to be understood in a second language allows an analysis engine implementing the methods of the present invention to avoid costly offline analysis and large databases, as the correct meaning of an ambiguous word in the first language may be determined with the help of the already known translation to a second language in which that word may be non-ambiguous.

A straight-forward way for taking advantage of the availability of the analyzed text in two different languages is by first independently and separately analyzing the text in each of the two languages, and then combining the two results, or validating one result using the other.

For example, if the analyzed text is available in both English and Hebrew, a full analysis of the text may be carried out once using only the English text as input, and a second time using only the Hebrew text as input. Consequently, each word in the text would have one of (i) a non-ambiguous meaning in both English and Hebrew (which must be the same meaning in both languages if the translation is accurate), (ii) an ambiguous meaning in English and a non-ambiguous meaning in Hebrew, (iii) a non-ambiguous meaning in English and an ambiguous meaning in Hebrew, (iv) an ambiguous meaning in both English and Hebrew. For cases (ii) and (iii) the non-ambiguous meaning of the word is selected from the appropriate language. For case (iv) the attempt to resolve the ambiguity fails, and other means (for example a third language) may be used for resolving the ambiguity.

This method of using two versions of the analyzed text in two different languages for selecting the correct meaning of ambiguous words provides better results than the prior art statistical methods, as it eliminates or reduces the dependency on statistical data which introduces a high degree of uncertainty and error into the selection process.

In some cases, the second language may be used only if the analysis of the text in the first language resulted in ambiguity. As such, if the analysis of the text in the first language resulted in each of the words having a single meaning, there is no need for analysis of the text in the second language.

In such cases, a method for taking advantage of the availability of the analyzed text in two different languages is by using the second language only to understand the meaning of words that were identified as ambiguous when analyzing the text in the first language. This process may include:

-   -   a. Preparing in advance a list of all words in a first language         that have multiple meanings. The list may be a stand-alone list         containing only the ambiguous words of the first language, or it         may be a database or a list containing all the words of the         first language, with the ambiguous words marked by an “ambiguity         flag”. Optionally, the list of ambiguous words may contain the         corresponding potential translations in a second language.     -   b. Scanning the text to be analyzed using the version in the         first language. For each word in the text, determining whether         the word is ambiguous or non-ambiguous in the first language.         The determination may be made by looking the word up in the         ambiguous words list. Non-ambiguous words are resolved, or         understood, without referring to the second language version of         the analyzed text, whereas for some or all of the ambiguous         words encountered during the scan the second language version of         the analyzed text is consulted. If the meaning of the word in         the second language which corresponds to the ambiguous word, is         non-ambiguous in the second language, i.e. the corresponding         word has only one meaning in the second language, that meaning         is taken to be the correct meaning of the ambiguous word in the         first language as well.     -   c. If the corresponding word in the second-language text is also         ambiguous, another methodology may be used for disambiguating         the word, such as, for example, finding a third language version         of the text (if available) and analyzing the meaning of the         corresponding word in the third language.

The above method is much more efficient and inexpensive to implement than the straight-forward method described before it, as it does not require an analysis of all words in the second language text.

In the context of the present application, the term “segment of text” relates to any portion of text, which may be a single word, multiple words—whether or not comprising a known phrase, a clause, a phrase, a sentence, multiple sentences, a paragraph, or multiple paragraphs. The term “segment of text” does not require or imply that the portion of text corresponding to the segment is a subset of a larger portion of text.

In the context of the present application, the term “content of a segment of text” relates to a full or partial meaning of the segment of text. A “full meaning” of the segment is an understanding of the meaning of the text sufficient for generating a full and accurate translation of the segment of text into a second language. A “partial meaning” of the segment is an understanding of the meaning of the text sufficient for identifying at least one concept or topic appearing in the segment of text, even if the understanding is insufficient for generating a full translation of the segment of text into a second language.

In the context of the present application, the term “outputting” from a device, for example of a message or content, relates to providing the message or content in any suitable way to another entity, such as displaying the message or content on a screen, playing the message or content as audio, sending the message or content to another device via a communication line or a communication network, or storing the message or content into a non-transitory computer readable storage medium.

In the context of the present application, the term “message” relates to any type of information, such as, for example, a recommendation, a translation, an analysis, and the like.

In the context of the present application, the term “video media content” relates to any segment of video of any length and in any format, whether or not the segment of video is associated with a corresponding audio segment.

In the context of the present application, the term “media playing device” relates to any device capable of playing video media content, such as a desktop computer, a laptop computer, a tablet computer, a smartphone, a DVD player, a television, and the like.

In the context of the present application, the terms “subtitles”, “captions”, and “closed-captions” all relate to text intended to be displayed on a screen of a media playing device during playing of video media content to provide additional or interpretive information. This includes transcription of the audio associated with the video media content as it occurs, description of non-speech elements in the audio, and translation of the audio from a primary language into one or more alternative languages. The text of the subtitles, captions, or closed captions may be visible or invisible when the video media content with which they are associated is being played on the media playing device.

In the context of the present application, the term “ambiguous word” relates to a word having multiple distinct meanings, or interpretations, in a specific language. The translation of an ambiguous word in a first language to a second language may continue to be ambiguous, or may resolve the ambiguity.

The principles, uses and implementations of the teachings herein may be better understood with reference to the accompanying description and figures. Upon perusal of the description and figures present herein, one skilled in the art is able to implement the invention without undue effort or experimentation.

Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its applications to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention can be implemented with other embodiments and can be practiced or carried out in various ways. It is also understood that the phraseology and terminology employed herein is for descriptive purpose and should not be regarded as limiting.

Reference is now made to FIGS. 1A and 1B, which are schematic block diagrams of two embodiments of devices for determining the meaning of a segment of text, using a translation of the text into another language, according to an embodiment of the teachings herein.

Martin, all of which are incorporated herein by reference as if fully set forth herein. In some embodiments, the instructions 130 a include instructions for accessing a database or knowledge repository 140, which may be functionally associated with processor 120 a, for example via a communication system or a communication line.

Turning to FIG. 1B, it is seen that a device 100 b thereof is substantially similar to device 100 a of FIG. 1A, with slight differences as described herein. As such, the reference numerals of FIG. 1B correspond to those of FIG. 1A.

Device 100 b includes a processor 120 b substantially as described hereinabove with respect to FIG. 1A. The processor 120 b of FIG. 1B is associated with a text source 125 a, and with an output destination 125 b.

In some embodiments, the text source 125 a may be a media playing device or a set top box as described hereinabove with reference to FIG. 1A. In other embodiments the text source may be a website, an electronic book, a local computer or any other suitable text source.

In some embodiments, the output destination 125 b is a display screen, such as a display screen associated with a desktop computer, laptop computer, tablet computer, smartphone, or television. In some embodiments, the output destination 125 b may be a computer storage, such as a hard disk, a solid-state drive, a removable storage device or the like.

Some of the instructions stored in the storage medium 122 b are different from those stored in storage medium 122 a. Specifically, the storage medium includes at least the following instructions:

instructions 146 to obtain a first segment of text in a first language;

instructions 148 to obtain a second segment of text in a second language, the second segment of text being a translation of the first segment of text;

instructions to determine content of the first segment of text in accordance with a predefined analysis rule, where the rule is implemented by instructions including:

-   -   instructions 150 a to attempt to determine content of the first         segment of text by analyzing the first segment of text without         using the second segment of text;     -   instructions 150 b to identify, during the analysis of         instructions 150 a, one or more ambiguous words in the first         segment of text which have multiple meanings in the first         language; and     -   instructions 150 c to be carried out for at least one identified         ambiguous word, and in some embodiments for all identified         ambiguous words, to identify a corresponding word in the second         language that is a translation of the identified ambiguous word,         and that is not ambiguous in the second language (has only one         meaning in the second language), and to assign the unambiguous         meaning of the corresponding word in the second language to the         identified ambiguous word; and

instructions 152 to output a message based on the determined content of the first segment of text.

As discussed hereinabove with reference to FIG. 1A, the instructions 150 a may include instructions for carrying out the methodologies disclosed in U.S. Pat. Nos. 4,931,935; 4,980,829; 5,056,021; 5,109,509; 5,424,947; 5,590,039; 5,761,631; 5,794,050; 5,878,386; 6,292,771; 6,505,157; 6,684,201; 6,952,666; 7,739,102; 8,463,593; 8,712,759; 2001/0024902; 2004/0078190; and 2005/0080613, as well as in http://anthology.aclweb.org/P/P91/P91-1017.pdf, http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.965.7393&rep=rep1&type=pdf, and “Speech and Language Processing” by Daniel Jurafsky and James H. Martin. In some embodiments, the instructions 150 a include instructions for accessing a database or knowledge repository 140, which may be functionally associated with processor 120 b, for example via a communication system or a communication line.

Reference is now additionally made to FIG. 2, which is a flow chart of an embodiment of a method for determining the meaning of a segment of text, using a translation of the text into another language, according to an embodiment of the teachings herein, using the devices 100 a and 100 b of FIGS. 1A and 1B, respectively.

For the sake of example, the method of FIG. 2 will be described with respect to the example mentioned hereinabove, in which the segment of text is the sentence “the days of the paper calendar are numbered”, and the intended meaning is that each page in the paper calendar has a number printed on it.

As seen in FIG. 2, initially the processor (120 a or 120 b) obtains a first segment of text in a first language, at step 200, and a second segment of text in a second language, at step 202. The second segment of text is a translation of the first segment of text. In the present example, the first segment of text is the English sentence “the days of the paper calendar are numbered” and the second segment of text is the corresponding Hebrew sentence “

”

In some embodiments, such as when using device 100 a of FIG. 1A, the first and second segments of text comprise part of subtitles of video media content played by media playing device 124 a. In some such embodiments, the first and second segments of text are obtained from the media playing device 124 a or from the set-top box 124 b.

In other embodiments, such as when using device 100 b of FIG. 1B, the first and second segments of text may be any suitable segments of text, and may include segments taken from a website, a book, a newspaper, a magazine, or from any other suitable source of text. In some such embodiments, the first and second segments of text are obtained from the text source 125 a, either directly or via a communication line or a communication network.

The processor (120 a or 120 b) proceeds to analyze the text in accordance with an analysis rule, as described hereinbelow. It is a particular feature of some embodiments of the teachings herein that analysis of the text is carried out in real-time. For example, in embodiments in which the segment of text comprises subtitles of video media content, the analysis of the text is carried out as the video media content is being played on media playing device 124 a. In other embodiments, the analysis of the text may be carried out as the segment of text is being obtained, for example as an electronic book is being read.

At step 204, the processor (120 a or 120 b) attempts to determine the content of the first segment of text, by analyzing the first segment of text without using the second segment of text. During the analysis of step 204, one or more ambiguous words in the first segment of text, which have more than one meaning in the first language, may be identified by the processor, as seen at step 206.

Analysis of the first segment of text may be carried out using any suitable methodology. For example, analysis of the first segment of text may be carried out using methodologies disclosed in U.S. Pat. Nos. 4,931,935; 4,980,829; 5,056,021; 5,109,509; 5,424,947; 5,590,039; 5,761,631; 5,794,050; 5,878,386; 6,292,771; 6,505,157; 6,684,201; 6,952,666; 7,739,102; 8,463,593; 8,712,759; 2001/0024902; 2004/0078190; and 2005/0080613, as well as in http://anthology.aclweb.org/P/P91/P91-1017.pdf, http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.965.7393&rep=rep1&type=pdf, and “Speech and Language Processing” by Daniel Jurafsky and James H. Martin.

Identification of ambiguous words may be carried out by any suitable means. In some embodiments, a list of words in the first language which have more than one meaning in that language is compiled in advance, and for each word in the first segment of text it is determined whether or not the word is included in the pre-compiled list.

In the current example, the processor determines the meaning of the words “days”, “paper”, and “calendar”, and identifies the word “numbered” as being ambiguous.

At step 208, the processor evaluates whether ambiguous words have been found in the first segment of text. If ambiguous words have been found, one such word is selected at step 210, and at step 212 the processor identifies in the second segment of text a word in the second language, which corresponds to the selected ambiguous word. At step 214, the processor evaluates whether the identified corresponding word is ambiguous in the second language, possibly using a pre-compiled list of ambiguous words of the second language.

In the present example, the selected (and only) ambiguous word is “numbered”, which corresponds to the Hebrew word “

”. As discussed hereinabove, the two meanings of the word “numbered” in English translate into two different words in Hebrew, with “

” meaning “marked by numbers” and “

” meaning “limited in number”. As such, and due to the fact that the Hebrew word “

” has no meanings other than “marked by numbers”, the Hebrew word corresponding to the ambiguous word “numbered”, is non-ambiguous in the second segment of text.

If the corresponding word in the second language is unambiguous, as in the example above, the meaning of the corresponding word is taken as the correct meaning of the ambiguous word in the first language, at step 216, and the meaning of the ambiguous word is resolved. Returning to the example, the meaning of the Hebrew word “

”—“marked by numbers”—is assigned to the English word “numbered” in the first segment of text.

Otherwise, if the corresponding word is ambiguous in the second language, at step 218 other disambiguation methodologies are used to resolve the meaning of the ambiguous word.

In some embodiments, in order to resolve the meaning of the ambiguous word at step 218, the disambiguation process of steps 212 to 218 may be repeated using a third segment of text in a third language, the third segment of text being a translation of the first and second segments of text into the third language.

Once the selected ambiguous word is resolved, the processor returns to step 208 to see whether any words are still ambiguous, and have not yet been resolved. If there are unresolved ambiguous words, the process returns to step 210, and a new ambiguous word is selected for processing.

If all the ambiguous words have been resolved, or if at step 208 it is determined that no ambiguous words were found, the entire content of the first segment of text is determined, and the processor outputs a message based on the determined content of the first segment of text at step 222. In the embodiment of FIG. 1A, the message is outputted to the set-top box 124 b or to the media playing device 124 a. In the embodiment of FIG. 1B, the message is outputted to the output destination 125 b.

In some embodiments, such as when using device 100 a of FIG. 1A and when the first segment of text comprises subtitles of video media content, the message may comprise a recommendation for content associated with the video media content or with the first segment of text. For example, the message may include a recommendation for additional video media content of a similar genre, or relating to similar topics.

In some embodiments, for example when using device 100 b of FIG. 1B, the message may comprise a textual description of the determined content of the first segment of text. In some embodiments, information related to the determined content of the first segment of text may be obtained by the processor, and the message may include the obtained information. In some embodiments, the processor may translate the first segment of text into a third segment of text in a third language, based on the determined content of the first segment of text, and the message may include the third segment of text.

Nos. 4,931,935; 4,980,829; 5,056,021; 5,109,509; 5,424,947; 5,590,039; 5,761,631; 5,794,050; 5,878,386; 6,292,771; 6,505,157; 6,684,201; 6,952,666; 7,739,102; 8,463,593; 8,712,759; 2001/0024902; 2004/0078190; and 2005/0080613, as well as in http://anthology.aclweb.org/P/P91/P91-1017.pdf, http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.965.7393&rep=rep1&type=pdf, and “Speech and Language Processing” by Daniel Jurafsky and James H. Martin. In some embodiments, the instructions 350 a include instructions for accessing a database or knowledge repository 340, which may be functionally associated with processor 320 b, for example via a communication system or a communication line.

Reference is now additionally made to FIG. 4, which is a flow chart of an embodiment of a method for determining the meaning of a segment of text, using a translation of the text into another language, according to another embodiment of the teachings herein, using the devices 300 a and 300 b of FIGS. 3A and 3B, respectively.

FIG. 4 is described herein with respect to another example, in which the meaning of the English sentence “The restaurant hosted a large party” is being determined. The word ‘party’ in English can be used to mean ‘a group of people’ or ‘a celebration’. As such, the sentence can be interpreted as meaning “the restaurant hosted a large celebration” or as meaning “the restaurant hosted a large group of people”. By contrast, in Hebrew, a party in the meaning of a group of people is ‘

’ and a party in the meaning of a celebration is ‘

’. In the present example, the intended meaning is that relating to a large celebration. As seen in FIG. 4, initially the processor (320 a or 320 b) obtains a first segment of text in a first language, at step 400, and a second segment of text in a second language, at step 402. The second segment of text is a translation of the first segment of text. In the present example, the first segment of text is the English sentence “The restaurant hosted a large party”, and the second segment of text is the corresponding Hebrew sentence “

”.

In some embodiments, such as when using device 300 a of FIG. 3A, the first and second segments of text comprise part of subtitles of video media content played by media playing device 324 a. In some such embodiments, the first and second segments of text are obtained from the media playing device 324 a or from the set-top box 324 b.

In other embodiments, such as when using device 300 b of FIG. 3B, the first and second segments of text may be any suitable segments of text, and may include segments taken from a website, a book, a newspaper, a magazine, or from any other suitable source of text. In some such embodiments, the first and second segments of text are obtained from the text source 325 a, either directly or via a communication line or a communication network.

The processor (320 a or 320 b) proceeds to analyze the text in accordance with an analysis rule, as described hereinbelow. It is a particular feature of some embodiments of the teachings herein that analysis of the text is carried out in real-time. For example, in embodiments in which the segment of text comprises subtitles of video media content, the analysis of the text is carried out as the video media content is being played on media playing device 324 a. In other embodiments, the analysis of the text may be carried out as the segment of text is being obtained, for example as an electronic book is being read.

At step 404, the processor (420 a or 420 b) attempts to determine the content of the first segment of text, by analyzing the first segment of text without using the second segment of text. Analysis of the first segment of text may be carried out using any suitable methodology. For example, analysis of the first segment of text may be carried out using methodologies disclosed in U.S. Pat. Nos. 4,931,935; 4,980,829; 5,056,021; 5,109,509; 5,424,947; 5,590,039; 5,761,631; 5,794,050; 5,878,386; 6,292,771; 6,505,157; 6,684,201; 6,952,666; 7,739,102; 8,463,593; 8,712,759; 2001/0024902; 2004/0078190; and 2005/0080613, as well as in http://anthology.aclweb.org/P/P91/P91-1017.pdf, http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.965.7393&rep=rep1&type=pdf, and “Speech and Language Processing” by Daniel Jurafsky and James H. Martin.

In the present example, the processor attempts to determine the meaning of the English sentence ‘The restaurant hosted a large party’.

At step 406, the processor evaluates whether the content of the first segment of text was successfully determined at step 404. The analysis is considered successful if every word in the first segment of text is resolved, and there is no ambiguity as to the content of the first segment of text. Such ambiguity may arise from the first segment of text including ambiguous words, which have more than one meaning in the first language. In the present example, the content of the sentence is not successfully determined, as it is unclear whether the meaning of the sentence is that the restaurant hosted a large group of people or that the restaurant hosted a large celebration.

If the analysis is determined to be unsuccessful, at step 408 the second segment of text is analyzed to determine content of the second segment of text, substantially as described hereinabove at step 404. At step 410, the processor evaluates whether the content of the second segment of text was successfully determined at step 408. In the present example, the corresponding Hebrew sentence, ‘

’ is unambiguous and the meaning thereof is clearly that the restaurant hosted a large celebration.

If the content of the second segment of text was successfully determined, results of the analysis of the second segment of text are used to determine the content of the first segment of text, at step 412. In the present example, it is understood that the sentence ‘The restaurant hosted a large party’ means that the restaurant hosted a large celebration, or that a large party occurred at the restaurant.

Otherwise, if the content of the second segment of text was not successfully determined, at step 414 other methodologies are used to determine the meaning of the first segment of text.

In some embodiments, in order to determine the meaning of the first segment of text at step 414, steps 408 to 412 may be repeated using a third segment of text in a third language, the third segment of text being a translation of the first and second segments of text into the third language.

Once the content of the first segment of text is successfully determined, either at step 404 or following steps 412 or 414, the processor outputs a message based on the determined content of the first segment of text at step 416. In the embodiment of FIG. 3A, the message is outputted to the set-top box 324 b or to the media playing device 324 a. In the embodiment of FIG. 3B, the message is outputted to the output destination 325 b.

In some embodiments, such as when using device 300 a of FIG. 3A and when the first segment of text comprises subtitles of video media content, the message may comprise a recommendation for content associated with the video media content or with the first segment of text. For example, the message may include a recommendation for additional video media content of a similar genre, or relating to similar topics.

In some embodiments, for example when using device 300 b of FIG. 3B, the message may comprise a textual description of the determined content of the first segment of text. In some embodiments, information related to the determined content of the first segment of text may be obtained by the processor, and the message may include the obtained information. In some embodiments, the processor may translate the first segment of text into a third segment of text in a third language, based on the determined content of the first segment of text, and the message may include the third segment of text.

In some embodiments, the processor may output the message at step 416 by providing the message to a display device functionally associated with the processor to be visually displayed thereon. For example, in the embodiment of FIG. 3A, the message may be provided to the set-top box 324 b or to the media playing device 324 a for display on a screen associated with the media playing device. As another example, in the embodiment of FIG. 3B, the output destination 325 b may be a display screen, and the message outputted by the processor may be displayed thereon.

In some embodiments, the processor may output the message at step 416 by providing the message to a non-transitory computer readable storage medium functionally associated with the processor to be stored therein. For example, in the embodiment of FIG. 3B, the output destination 325 b may be a hard-disk drive of a server or other storage medium, and the message outputted by the processor may be stored therein.
